三个不同地区九叶青花椒主要营养成分比较

Comparison of Main Nutritional Components of Zanthoxylum Jiuphylla in Three Different Regions

选取重庆江津、安顺板贵和六枝龙河三个不同地区的九叶青花椒为材料,采用国家标准比较其主要营养成分、重金属元素和农残含量。结果表明:三个不同地区的九叶青花椒中精油含量、花椒含油量均差异显著,其中精油含量以六枝龙河最高,重庆江津最低;青花椒含油量安顺板贵显著高于其他两个地区,重庆江津的含油量最低;六枝龙河的九叶青花椒中不挥发性乙醚提取物含量显著高于重庆江津的(P<0.05)。六枝龙河引种的九叶青花椒营养品质较原产地重庆江津的高,且香味较浓,重金属元素和农残含量符合国家食品安全标准,很有必要在当地进行推广。

The Zantloxylunarmatum var.Novemfolius from different regions were selected,and their contents of main nutrients,heavy metal and pesticide residues were measured by the methods of national food standards.Results showed that the essential oil content of var.novemfolius in the Longhe Town of Liuzhi city was higher than in the Jiangjin County of Chongqing City,and the essential oil contents of var.novemfolius were significantly different in three different regions.In addition,the content of non-volatile ether extract of var.novemfolius in Longhe Town of Liuzhi city was significantly higher than that in the Jiangjin County of Chongqing City.In summary,the nutritional quality of Zantloxylunarmatum var.novemfolius from Longhe Town of Liuzhi city with strong fragrance is higher than that from Jiangjin County of Chongqing City.The content of heavy metal and pesticide residues of Zantloxylunarmatum var.novemfolius from the Longhe Town of Liuzhi city meets the national food safety standards,so it is necessary to promote it locally.
